## a simplified form of equation...

simpl.mw

this file is a simple format of original file.

simpl.mw

## is not possible?...

It is not possible to do by maple?

Thank you

## EXAMPLE FOR EXPLAIN...

Thanks so much. I provided a sample example,

I want to take integral by parts from equation (13.12) in the attached file below.

Best Regards

## if possible??...

if possible to solve this equations or not?

Best

thank you

## 3D...

Thank you.

Recently I have been founded that Maple in new its version is capable of solving 3D problems!!

Maybe I am in mistake.

Thanks so much.

Best.

## provide code...

Thank you daer Preben. I write the equations in maple.

If you need additional assumptions, you can consider it.

Thanks so much.

## Direct Search...

Thank you.

How I can use DirectSearch for these equations?

Thanks

## Newtons Method...

is possible to write a code similar to the attached below that can solve equations by Newtons Method?

Thank you

## fsolve problem!!!...

Thank you so much dear Acer;

Only my problem is fsolve.

Because when I change the value N :=7 ; M := 7 to N := 11; M := 11.

fsolve can not gain an answer in a new file as attached below!!

is possible that I use another method, for example, NewtonsMethod?

## no matrices !!!...

Thank you. No the final system ( SYSPDE) not expected to contain matrices and 'SYSPDE' only must have a simple sum of (scalar) products.

I don't know why matrices are added in pde5!!!

## old system is working!!!...

Thanks so much, dear Acer and tomleslie and Preben.

Before I solved similar equations that I attached bellow, they are working now.

In the new system, I added only pde4 and pde 5, and for now, I do not know why it is not working well.

## non-scalar nonsense...

Thank you.

If possible please edit file and send it for me.

Thank you

## ?...

Thank you.

I do not know your mean completely in this regard.

Best,

Hello,

I could not gain an answer.!!!

I have two questions.

what were the advantages to using DirectSearch package to solve equations? And second;

how I can use a convential method such as Newton-Raphson method?

Thank you
